[lvc-project] [PATCH v4] PCI: dwc: keystone: Fix NULL pointer dereference in case of DT error in ks_pcie_setup_rc_app_regs()

[Krzysztof Wilczyński]

Hello,

> If IORESOURCE_MEM is not provided in Device Tree due to any error,
> resource_list_first_type() will return NULL and
> pci_parse_request_of_pci_ranges() will just emit a warning.
> This will cause a NULL pointer dereference.
> Fix this bug by adding NULL return check.
> 
> Found by Linux Verification Center (linuxtesting.org) with SVACE.
